Executive  Summary    

Climate   change,   coastal   erosion,   sea-­‐level   rise,   and   coastal   storms   and   flooding   threaten   public   and  private   infrastructure   along   the   California   coast.  While   political  will   to   relocate   away   from   vulnerable  areas   remains   low,   federal,   state,   and   local   government   officials   seek   financially   practical   options   to  update   and   improve   coastal   flood   defenses.     Nature-­‐based   strategies   that   enhance   the   natural   flood  mitigation  benefits  of  coastal  ecosystems  could  be  an  effective  approach,  particularly  if  supported  with  federal  funding  through  the  FEMA  Hazard  Mitigation  Programs.    However,  local  jurisdictions  have  yet  to  leverage  FEMA  funding,  and  few  California  jurisdictions  have  pursued  nature-­‐based  strategies.    

To   identify  barriers   to  and  opportunities   for  nature-­‐based   strategies,  we   interviewed  city  and  county-­‐level  coastal  planners  and  emergency  officials  in  five  coastal  California  counties.  Selected  counties  were  vulnerable   to   coastal   flooding,   have   received   FEMA   hazard   mitigation   funding,   and   are   currently  engaged  with  the  Coastal  Resilience  Network  of  The  Nature  Conservancy  (TNC).      

Barriers  identified  by  respondents  include:    

• Lack  of  technical  standards  to  guide  implementation  and  evaluation;    • Low  levels  of  cross-­‐jurisdiction  coordination  among  local,  state,  and  federal  entities;    • Insufficient  funding  for  localized  data  collection,  strategic  planning,  and  regional  coordination;  and  • Lack  of  public  familiarity  with  nature-­‐based  strategies,  leading  to  a  lack  of  political  support.      

In   response   to   these   challenges,   we   propose   several   low-­‐cost,   no-­‐regret   solutions   that   could   be  undertaken  by  FEMA,  TNC,  or  other  interested  government  or  non-­‐government  organizations  to  assist  in  promoting   nature-­‐based   strategies   for   coastal   flood   mitigation   in   California.     A   full   list   of  recommendations  can  be  found  at  the  end  of  this  white  paper,  but  some  notable  examples  include:    

• Establishing   clear   technical   implementation   and  monitoring   and   evaluation   standards   for   nature-­‐based  strategies  that  satisfy  FEMA’s    feasibility  requirements  for  hazard  mitigation  funding;    

• Investing   in   cross-­‐agency   and   -­‐jurisdictional   communication   and   coordination,   to   include   funding  collaborative  projects  or  providing  greater  opportunities  for  in-­‐person  networking  and  coordination;  

• Providing   clearer   guidance   on  whether   and   how   nature-­‐based   strategies   can  meet   the   goals   and  priorities  of  hazard  mitigation  funding  programs;      

• Educating   local   officials   and   the   public   about   the   benefits   and   performance   of   nature-­‐based  strategies.    This  could  include  creating  an  online  “toolkit”  of  nature-­‐based  flood  mitigation  strategies  that  provides  information  on  technical  standards,  implementation,  monitoring,  and  cost.  

Implementing   these   suggestions   or   otherwise   addressing   the   barriers   identified   to   nature-­‐based  solutions   may   help   protect   California’s   coast   and   coastal   infrastructure   for   the   future.

Nature-­‐based   strategies   (NBS)   are  development   strategies   that  harness   the   functions   and  resources   contained   in   healthy  ecosystems   to   solve   existing  challenges,   while   maintaining   the  integrity   of   the   natural  environment.    These  strategies  rely  on   the   ingenuity   of   the   natural  world,   reducing   the   amount   of  time,   money,   and   effort   human  society   must   exert   to   keep   other  natural   processes   at   bay.     By  pursuing   nature-­‐based   strategies  to   coastal   hazards,   humans   avoid  degrading   the   environment   and  exacerbating  environmental  issues.  

 

 

Nature-­‐Based  Strategies  Provide  Flood  Mitigation  and  Minimize  Social  and  Ecological  Harms  

Coastal  areas  are  fraught  with  potential  hazards  such  as  flooding,  storm  surge,  sea   level  rise,  and  high  tides.     Traditionally,   humanity   has   fought   back  with   concrete   and   steel:   constructing   seawalls,   groins,  dikes,   bulkheads,   and   levies,   all   designed   to   hold   the   sea   back.     Unfortunately,   these   hard   structures  erode  coastal  habitat  around  them,  ultimately  shifting  damage  rather  than  absorbing  it.     In  addition  to  degrading   the  natural  coastal  area  and  harming  ecosystems  present   there,   structural  coastal  defenses  erode  the  physical  beach  area,  often  limiting  and  impeding  public  access  (Dugan  &  Hubbard,  p.  191).    In  many  states,  including  California,  such  consequences  may  not  align  with  the  interests  of  the  public.      

In   light   of   the   evolving   hazards   posed   by   sea   level   rise,   California   coastal   communities   in   the   coming  decades  will  have  to  make  difficult  choices  about  how  to  protect  shorelines  and  existing  development.    One  strategy  with  significant  potential  is  a  focus  on  nature-­‐based  strategies  (NBS).  

NBS  are  a  relatively  new  concept  in  development  planning,  but   they   have   the   potential   to   benefit   many   coastal  communities   while   simultaneously   supporting   vibrant  ecosystems   and   softening   the   divide   between   built   and  natural  environments.    One  area  where  these  benefits  can  clearly   be   seen   is   coastal   defense   and   coastal   hazard  mitigation  (Newkirk  &  Beck,  in  Craig  et.  al,  p.  20).      

NBS   offer   an   innovative   way   of   thinking   about   coastal  defenses.     Rather   than   battle   directly   against   tidal   forces  and   sea   level   rise,   NBS   enhance   the   way   natural   systems  absorb   and   minimize   flooding   and   inundation.     This  approach  –   replicating  and  encouraging  natural  conditions  that   lessen   the   severity   of   flooding   events   –   avoids  many  pitfalls   of   hard   structuring,   with   the   added   benefit   of  maintaining  natural  ecosystems  and  their  services.    

NBS   such   as   “living   shorelines”   are   often   less   costly   and  require  less  long  term  maintenance.    Unlike  seawalls,  which  lock   local  planners   into  years  of  battling  both  erosion  and  structural   integrity,   living  coastlines  provide  triple  benefits  by  “controlling  erosion,  maintaining  natural  coastal  processes,  and  sustaining  biodiversity”  (Swann,  p.  1).    These  outcomes  serve  long-­‐term  interests  of  both  the  public  and  the  natural  environment.  

Hazard  Mitigation  Is  the  Best  Opportunity  to  Change  Our  Approach  to  Coastal  Defense  

FEMA,  through  its  Hazard  Mitigation  Assistance  (HMA)  grant  programs,  provides  funding  to  states  and  local   communities   to   invest   in   resilience.1    Most   grants   are   awarded   and   used   in   the   aftermath   of   a  disaster,   when   the   community   is   most   aware   of   its   vulnerability   and  most   willing   to   act.     The   post-­‐

disaster   planning   process   gives   communities   the   chance   to   remedy   past   land-­‐use   mistakes   and   to  address  areas  where  development  is  unprotected  to  create  more  effective  solutions  and  a  more  resilient  public.     Structural   approaches   to   coastal   hazard  mitigation  have   long  been   the  norm,  and   remain   the  default   approach   in   many   coastal   areas,   but   this   does   not   mean   they   are   the   best   option   moving  forward,   especially   in   light   of   declining   coastal   wetland   ecosystems,   on-­‐going   beach   erosion,   and  accelerating  sea-­‐level  rise.      

Though   relatively  new   in   the  modern  hazard  mitigation   toolkit,   compared   to  existing  hard   structuring  strategies,   nature-­‐based   and   non-­‐structural   hazard   mitigation   strategies   address   coastal   threats   in   a  cost-­‐effective  manner,  without  causing  additional  damage   to   the  coastal   zone,  and  without  producing  the   false   sense   of   security   that   has,   in   the   past,   enabled   development   in   risk-­‐prone   areas   (American  Planning   Association,   p.   60).     It   is   crucial   to   seize   these   opportunities   for   a   new   vision   during   the  recovery   and   rebuilding   phase   following   a   disaster,  when   the   public   is   not   satisfied   to   simply   replace  what  has  already  failed  before.        

Local  Barriers  to  Adaptation  of  Nature-­‐Based  Strategies  in  California  Coastal  Communities  

Despite   the   opportunity   for   local   California   governments   to   integrate   non-­‐structural   coastal   hazard  mitigation   strategies   into   existing   plans   (or   to   apply   for   HMGP   or   PDM   funding   for   nonstructural  projects),  very   little  progress  has  been  made  to  reduce  the  reliance  of  planners  on  seawalls  and  other  hard  armoring  systems.    Simply  having  the  option  of  non-­‐structural  strategies  (and  data  to  support  their  merit)   does   not   mean   these   options   are   easily   pursued.     Non-­‐structural   solutions,   especially   nature-­‐based  strategies,  are  a  relatively  unusual  approach  to  coastal  hazard  mitigation,  and  many  barriers  exist  in  local  government  agencies  when  it  comes  to  adapting  plans  and  implementing  change.    

Research  done  by  Julia  Ekstrom  and  Susanne  Moser  on  the  subject  of  urban  climate  adaption  in  the  San  Francisco   Bay   Area   found   that   institutional   and   governance   constraints   impeded   effective   climate  adaptation   far   more   than   a   general   lack   of   information   regarding   climate   adaptation   strategies.    According  to  their  findings,  officials  tend  to  know  their  adaptation  options,  but  larger  political,  legal,  and  socioeconomic  conditions  prevent   them  from  acting   in  an  optimal   fashion   (2010,  p7).  One  goal  of  our  research  was  to  determine  whether  similar  institutional  and  governance  constraints  are  preventing  local  communities  from  implementing  nature-­‐based  strategies.    

Living  Shorelines:  An  Example  of  a  Nature-­‐Based  Strategy    

Living   shorelines  may  at   first   appear   soft,   permeable,   and  already   flooded  with  water,  but   the  marshy  wetlands  and  sandy  beaches  that  line  the  coastline  of  so  many  states  are  very  effective  at   protecting   coastal   areas.     If   allowed   to   function   naturally,   these   shorelines   resist   erosion,  keeping  some  distance  between  the  sea  and  human  property  and  infrastructure.    If  the  wetlands  and  beaches  are  healthy  and  well  maintained,   they  can  absorb  wave  power  and  remain   intact,  thereby  reducing  the  risk  of  waves  reaching  and  damaging  coastal  property.    

Many   states   along   the   Gulf   of   Mexico   have   maintained,   restored,   or   developed   “living  shorelines”   as   a  management   strategy   to   protect   coastal   property.     This   approach   includes   “a  suite  of  bank  stabilization  and  habitat  restoration  techniques  to  reinforce  the  shoreline,  minimize  coastal   erosion,   and   maintain   coastal   processes   while   protecting,   restoring,   enhancing,   and  creating  natural  habitat”  (Swann,  p.  2).

Our  research  team  selected  five  California  coastal  counties  that  have  previously  received  FEMA  hazard  mitigation  funding  and  are  currently  engaged  with  the  Coastal  Resilience  Network  of  TNC.    Due  to  their  engagement  with   both   FEMA   and   TNC,   these   communities   could   be   expected   to   benefit   from   FEMA  funding  for  NBS.    Understanding  why  such  communities  have  not  pursued  FEMA  funding  for  NBS  could  shed  light  on  the  barriers  to  NBS  implementation  in  coastal  California.  

We  interviewed  county  and  city  level  planning  and  emergency  response  officials  within  each  county.    All  respondents   are   involved   in   planning   or   implementing   hazard  mitigation   strategies   but   play   different  roles   in   building   coastal   resilience.     We   identified   initial   respondents   through   personal   connections,  online   searches,   and   publicly   available   FEMA   grant   information.     Respondents   were   asked   to  recommend   other   interview   subjects,   according   to   a   standard   snowball   sampling   technique.     Each  interview   lasted   30-­‐60  minutes,   and   included   questions   about   the   respondents’   duties,   experience   of  the  city  or  county  with  flooding  hazards,  current  mitigation  strategies,  familiarity  with  and  perceptions  of   nature-­‐based   flood  mitigation   strategies,   and   experience   (if   any)  with   the   FEMA   hazard  mitigation  funding  process.    Recurring   themes   in   the   interviews  were   identified  and  categorized,  drawing  on   the  Moser   and   Ekstrom   framework   for   adaptation   barriers.     Individual   respondents   are   not   identified   by  name   in   this   report,   and   their   locations,   job   titles,   or   other   identifying   information   is   altered   where  necessary  to  protect  their  anonymity.    

 

 

Respondents   identified   many   particular   barriers,   which   we   have   grouped   into   four   categories.     Each  category  is  discussed  below  and  suggestions  are  made  on  how  to  address  the  challenge.      

(1) Technical  and  Information  Barriers  (2) Coordination  Barriers  (3) Funding  Barriers  (4) Political  Will  Barriers  

Technical  and  Information  Barriers    Implementing   NBS   for   flood   mitigation   requires   planners   to   be   aware   of   NBS,   understand   their  limitations  and  benefits,  and  know  how  and  where   to  best  deploy  NBS.     Information  barriers  arose   in  several   contexts:   lack   of   familiarity   with   NBS   among   planners;   lack   of   relevant   or   localized   data   that  would   help   planners   decide   where   to   deploy   NBS;   absence   of   technical   standards   for   the   proper  implementation  of  NBS;  and  uncertainty  surrounding  monitoring  and  evaluation  practices.    

Familiarity  with  Nature-­‐Based  Flood  Mitigation  Strategies    

In   general,   a  majority   of   respondents  were   aware   of  NBS   as   an   approach   to   coastal   flood  mitigation.    This   was   particularly   true   among   younger   planners,   who   had   been   exposed   to   NBS   during   their  education,   and   planners   who  were   located   near   to   an   on-­‐going   NBS   project.     However,   respondents  noted  that  although  their  offices  may  be  aware  of  NBS,  they  are  most  familiar  with  “grey”  strategies  and  therefore  have  a  tendency  to  “do  what  they  know.”    This  lack  of  familiarity  makes  planners  nervous  to  undertake   what   they   see   as   an   unproven   course   of   action   (see   sections   below   on   lack   of   technical

standards  and  evaluation).  Planners  were  concerned  about  the  lack  of  precedent  with  NBS,  not  only  in  general  but  specifically  in  areas  similar  to  their  own  (with  similar  development  or  geographical  profiles).    

Planners  did  seem  open  to  the  potential  to  learn  more  about  NBS.    One  specifically  cited  the  need  for  a  toolkit  that  would  explain  how  NBS  work  and  how  much  they  cost.      Providing  such   information  could  help  ensure  that  uncertainty  does  not  become  an  excuse  for  inaction  (Moser,  p.  64).      

Relevant  and  Localized  Data    

Many   planners   cited   a   lack   of   data-­‐supported,   scientific   standards   for   how   to   create   NBS   flood  mitigation  projects  that  fit  the  specific  needs  of  their  communities.    Concerns  about  data  were  closely  tied  with   concerns  about   funding.     Lack  of   funding   is   a  prominent  and  clear   theme   that   runs   through  many   of   the   concerns   voiced   by   local   officials.     This   is   hardly   unique   to   NBS,   but   it   is   important   to  emphasize  how  often   interview  subjects  brought  up   the  concern   that  existing   funding   schemes   fail   to  help  them  acquire  the  data  they  feel  they  need  to  improve  their  coastal  flood  mitigation  planning.    

This  may  occur  due  to:  

1) a  local  funding  shortage,    2) funding  mechanisms  that  proscribe  the  type  of  data  that  can  be  collected,  or    3) funding   mechanisms   that   do   not   support   the   pre-­‐project   planning   efforts   that   may   be  

necessary  to  shift  flood  mitigation  towards  the  less  familiar  NBS.  

Proscribed  Data    

Respondents  often  noted  that  existing  funding  mechanisms  support  the  “wrong”  type  of  data  collection.  Planners  speculated   that   funding  agencies,   such  as  FEMA  and  the  Coastal  Commission,  may  only   fund  “less  useful”  but  tried  and  true  data  due  to  funding  constraints.    Planners  report  feeling  that  only  “less  expensive”  or  less  politically  sensitive  data  is  collected  and,  as  a  result,  planners  voice  some  skepticism  as  to  the  validity  of  existing  risk  assessments.    One  planner  went  so  far  as  to  question  whether  FEMA’s  flood   maps   were   “scientifically   valid”.     This   perception   of   inaccuracy   presents   major   challenges   for  decision-­‐making  and  coordination  efforts.    

As  the  benefits  of  NBS  often  become  most  apparent  when  sea  level  rise  is  considered,  failure  to  collect  and  consider  data  on  sea  level  rise  rates  can  affect  planners’  decisions.      For  instance,  one  official  voiced  doubt  in  the  utility  of  FEMA’s  flood  maps  due  to  their  omission  of  future  sea  level  rise  projections:    

“FEMA’s   updated   flood   maps   do   not   take   into   account   sea-­‐level   rise   and   are   very  conservative.    From  a  municipal  standpoint,  the  city  is  very  happy  to  have  less  aggressive  predictions   for   the   future   [because   it   does   not   require   them   to   re-­‐zone   future   flood  areas].”  

More  generally,  planners  believe  that  data  collection  efforts  do  not  provide  the  kind  of  information  they  feel   is  needed  to  pursue  NBS.    As  a  result,  planners  said  NBS  techniques  are  not  seriously  considered.  Planners  consistently  state  a  need  for  more   localized  data,   including   local   tide  gauges  or  groundwater  monitoring   systems   that  would   ensure   flood  mitigation   strategies   are   deployed   in   the  most   effective  manner,  rather  than  being  deployed  based  on  the  most  recent  disaster  or  along  political  lines.    

Planners   rely   heavily   on   data   about   their   community’s   risk   profile,   so   it   is   unrealistic   to   believe   that  officials   will   entrust   their   coastlines   and   infrastructure   to   newer,   innovative   solutions   without   a   full  picture  of  how  this  impacts  both  the  natural  and  built  environments.    Simply  put,  nature-­‐based  solutions  

Page 7: Executive)Summary)) · 2017. 6. 21. · Executive)Summary)) Climate)change,)coastal)erosion,)sea7levelrise,)and)coastalstorms)and)flooding)threaten)public)and) private)infrastructure)along)the)California

  6  

are   never   going   to   be   on   the   table   for   planners  without   useful,   and   relevant,   data   to   back   them   up.    There  is  a  general  sense  that  nature-­‐based  solutions  must  undergo  the  same  type  of  intensive  study  that  precedes  current  mitigation  strategies.        

Lack  of  Support  for  Pre-­‐Project  Planning      

As  NBS  are  a  relatively  unfamiliar  concept  for  hazard  mitigation  officers  and  city  planners,  planners  may  need   greater   support   from   funding   sources   for   planning   and   data   collection   efforts.     As   one   planner  noted,   if   funding   mechanisms   only   support   “shovel-­‐ready”   projects,   then   they   will   get   projects   that  require   a   shovel,   which   will   most   often   mean   doing   more   of   the   same:   more   traditional   structural  approaches.    Local  planners  also  frequently  feel  pressure  to  be  efficient  rather  than  creative,  leading  to  repetitive  management  practices.    Without  the  time  to  plan  and  fully  consider  NBS,  planners  default  to  their  traditional  approaches:    

“We’ve  invested  lots  of  resources,  and  we  want  to  protect  on  the  coast,  so  without  a  real  comprehensive  vision  of  what  something  else  would  look  like,  [switching  to  nature-­‐based  strategies]  is  politically  unattainable.”  

Funding  that  supported  greater  planning  efforts  would  provide  planners  with  the  space  to  promote  NBS.      

Technical  Standards    

In   addition   to   needing   data   on   where   to   most   effectively   deploy   NBS,   planners   require   technical  standards   on   how   to   implement   NBS.     FEMA   requires   hazard   mitigation   projects   to   be   technically  feasible,  which  usually  requires  the  project  to  conform  to  existing  engineering  standards,  but  there  are  few  existing  standards  for  NBS.  Lacking  technical  standards,  planners  view  NBS  as  “risky”  and  untested  alternatives  to  seawalls  and  levees.  

“[How   can  we]   gauge   the   effectiveness   of   nature-­‐based   strategies  when   there   are   no  technical  standards”?  

“We’re  asking  public  works  people  to  make  these  decisions,  and  they  like  to  build  things  that  work,   so   they   know   how   to   design   a   seawall   and   the   life   expectancy.   They   don’t  know  how  to  do  managed  retreat  and  beach  nourishment  and  know  [those  approaches]  will   have   the   same   level   of   certainty   that   needs   to   happen   to   make   the   mayor   and  everyone  else  happy….  We  don’t  have  the  expertise  for  these  [nature-­‐based]  strategies.”  

In   part,   this   uncertainty   is   due   to   the   lack   of   research   and   data   on   engineering   standards   for   NBS   in  California,  especially  in  developed  coastal  areas.    Studies  of  nature-­‐based  coastal  flood  mitigation  in  the  United   States   have   generally   been   limited   to   the   Gulf   States   (Barbier   et  al.,   2013;  Cobell   et  al.,   2013;  Peyronnin  et  al.,  2013;  Reguero  et  al.,  2014).  Outside  of  the  Gulf,  existing  research  includes:    

• The   U.S.   Army   Corps   of   Engineers   provides   a   list   of   potential   performance   metrics   to  measure  the  success  of  a  nature-­‐based  project  in  various  coastal  ecosystems,  but  there  are  few   examples   where   these   metrics   have   been   quantified   (US   Army   Corps   of   Engineers,  2013);      

• One  California  study,  “Quantifying  the  Engineering  Function  of  Coastal  Habitats  in  Flood  Risk  Reduction,”  is  ongoing,  but  results  have  not  yet  been  published  in  full  (Narayan  et  al.,  2015);    

• A  study  of  costs  and  benefits  of  using  tidal  wetlands  for  flood  protection  in  the  San  Francisco  Bay  Area  describes   the   flood  protection  benefits  of   tidal  wetlands  but  no   technical  guides  for  implementation  are  provided  (Lowe,  2013).

Potential  Solutions  to  Technical  and  Information  Barriers    

• Develop  technical  engineering  standards  to  guide  the  implementation  of  NBS;  and  standard  monitoring,  evaluation,  and  assessment  processes  to  document  the  performance  of  NBS.    

• Create  an  online  “toolkit”  of  nature-­‐based  flood  mitigation  strategies.  Include  information  on  technical  standards,  implementation,  monitoring,  costs,  and  when  and  where  particular  NBS  are  most  appropriate.    Identify  success  stories  in  California  to  serve  as  examples.    

• Clarify  funding  guidelines  to  expressly  and  explicitly  state  whether  NBS  are  eligible;  develop  a  “Frequently  Asked  Questions”  set  focused  on  NBS.  In  particular,  FEMA  needs  to  clarify  how  NBS   information   can   be   used   in   the   cost-­‐benefit   analysis   tools.     Make   information   from  successful   hazard  mitigation   funding   applications   publically   available   so   other   jurisdictions  can  see  how  those  grants  compiled  their  application  materials.    

• Provide  funding  for  data  collection  that  addresses  the  unique  needs  of  NBS;  this  may  require  funding  for  localized  data  collection  or  additional  planning  efforts.    

• Hold  workshops  on  the  role  of  NBS  in  flood  mitigation.    This  would  be  most  effective  if  held  by  or  in  collaboration  with  FEMA  or  other  hazard  mitigation  offices  and  if  held  in  person.    

• Call   for   more   academic   studies   to   focus   on   the   performance   of   NBS   flood   mitigation   in  California.      

Meta-­‐analyses   exist   to   support   the   argument   that   NBS   can   be   successful   if   implemented   properly  (Gedan  et  al.,  2010;  Pace,  2011),  and  case  studies   from  Europe  provide   tips  on  what  makes  a  nature-­‐based  project  work.    While  useful  in  illustrating  that  success  is  possible,  these  studies  only  highlight  the  need  for  more  site-­‐specific  and  quantitative  analysis  and  more  specific  procedures  in  California  if  NBS  is  to  be   implemented  broadly.     FEMA,  TNC,  and  other   federal  and  state  agencies   could  make  significant  strides  towards  promoting  nature-­‐based  flood  mitigation  strategies  by  developing  technical  engineering  standards  for  the  implementation  of  NBS.    

Monitoring  and  Evaluation    

Once   NBS   are   implemented,   it   is   still   necessary   to   monitor   and   evaluate   their   performance.     Such  monitoring  should  include  various  approaches:  “including:  physical,  biological  and  ecological  monitoring;  monitoring   of   sedimentation   and   erosion/accretion;   monitoring   impacts   to   selected   habitats;   and  monitoring  of  sea  defenses”  (Doswald  &  Osti,  p.  23).    Benefits  of  monitoring  include:  

• To   convince   local   stakeholders,   including   decision-­‐makers,   property   owners,   and   the  community,  that  a  nature-­‐based  strategy  will  work  in  their  particular  case;      

• To  assure  decision-­‐makers  that  these  strategies  have  a  beneficial  effect  on  the  ecosystem  and  strengthen  its  defenses;      

• To  provide  a  success  story  with  numerical  evidence  as  “a  powerful  tool  for  advocating  the  use  of  ecosystem-­‐based  approaches”  (Doswald  &  Osti,  p.  34).  

To  create  a  solid  strategy  and  work  plan  for  nature-­‐based  solutions  in  California,   local  decision  makers  need  more  than   just  stories  of  success   in  other  parts  of   the  world:   they  need  access   to  data   they  can  apply   to   their   own   jurisdictions.       Once   localized   data   is   acquired,   local   decision-­‐makers   need   either  access  to  experts  who  can  interpret  the  data  or  access  to  a  standardized  protocol  that  can  aid  decision-­‐makers  in  interpreting  the  data  themselves  so  they  have  confidence  in  the  needs  of  their  coastline.    In  addition,   more   examples   of   how   to   properly   implement   these   strategies   in   California   from   an  engineering   standpoint   are   needed,   as   are   examples   of   how   to   consciously   engage   community  stakeholders  in  a  way  that  leads  to  the  most  effective  collaboration.

Coordination  and  Collaboration  Barriers    Flood  mitigation  strategies,  whether  traditional  structural  approaches  or  NBS,  affect  the  flow  of  water  and  sediment  across  more   than   the   just   the  project   site.    As  a   result,   these  efforts  are  most  effective  when   performed   in   coordination   with   neighboring   jurisdictions.     However,   respondents   in   our   study  note  that  both  cross-­‐jurisdictional  and  cross-­‐agency  coordination  are  extremely  rare.      Officials  recognize  this  as  a  barrier  to  change  and  in  particular  a  barrier  to  the  use  of  NBS.    

Academic  studies  note  the  importance  of  collaboration  in  environmental  governance  generally  and  NBS  specifically.    Doswald  and  Osti,   in   their  meta-­‐analysis  of  European   flood  mitigation   studies,   concluded  that   “large   cooperative   projects,   involving   different   partners,   are   good   opportunities   to   exchange  learning  and  a  conduit  for  innovative  ideas”  (2011).  They  highlight  a  multinational  project  called  WAVE  (Water   Adaptation   is   Valuable   to   Everyone)   that   brought   “regional   partners   in   the   Netherlands,   UK,  France,   Belgium,   and   Germany   together   to…   reduce   flooding   and   manage   water   resources   more  sustainably   and   make   the   environment   more   resilient   to   climate   change”   using   “ecosystem-­‐based  adaptation   measures”   including   “wetland   preservation,   tree   planting,   river   restoration,   rainwater  collection,   sustainable   agriculture   and   renewable   energy   utilization”   (Doswald   &   Osti,   p.19).   These  findings  concur  with  more  general  studies  on  flood  mitigation  and  public  management  that  have  found  collaboration   and   stakeholder   engagement   to   be   necessary   components   (e.g.,   Brody   et   al.,   2010;  McGuire,  2006;  Innes  &  Booher,  2003).    

Coordination   issues   in   California   are   both   horizontal   in  nature   (e.g.,   among   cities)   and   vertical   (e.g.,   between  cities   and   counties,   or   between   cities   and   state   or  federal   agencies).     Open   communication   channels   are  vital   for   sharing   best   practices   and   gaining   wider  acceptance  of  NBS.        

However,  coordination  along  the  California  coast  to  date  tends   to   be   project-­‐specific.     This   approach   limits  planners’   ability   to   seriously   consider   nature-­‐based  mitigation  strategies  because  the  coordination  is  already  focused   on   a   pre-­‐determined   project,   usually   a  traditional   structural   project.     If   NBS   are   to   gain  wider  acceptance   among   California   planners,   there   needs   to  be   a   forum   for   officials   to   communicate   ideas,   issues,  and  best  practices  outside  of  the  context  of  any  specific  project.    Such  coordination  would  benefit  not  only  NBS,  but  all  types  of  coastal  planning  efforts.    

One   local   official   spoke   of   in-­‐person   seminars   held   by  FEMA  around  five  years  ago  where  she  met,  networked,  and   collaborated   with   people   from   many   other  jurisdictions.     Today   these   FEMA   seminars   have   been   replaced   by   webinars,   which   are   useful   for  disseminating   information  efficiently  but  cut  out  the  interactive  personal  component  that   is  so  vital  to  spurring  collaboration.    Planners  want  to  remain  informed  as  to  what  others  in  their  field  are  doing,  but  they  note  that  this  is  difficult  to  do  given  resource  limitations  and  the  project-­‐based  funding  approach.    

Example   of   Successful   Coordination:  Santa   Barbara   and   Humboldt  Counties    

The   County   of   Santa   Barbara   is  currently   undertaking   a   project   to  model   sea   level   rise.     Both   city-­‐level  and   county-­‐level   planners   in   Santa  Barbara   are   engaging   in   productive  dialogue   about   the   ongoing   project  and   its   impacts.   Similarly,   Humboldt  County   established   a   very   effective  Sea   Level   Rise   Adaptation   Planning  Group,  which  brought   in   stakeholders  and   officials   from   throughout   the  county   to   discuss   the   impacts   of   sea  level   rise.     Even   after   completion,  members   of   this   group   still   share  information   and   remain   connected  today.

Finding  a  way   to   spur  more   in-­‐person  networking  and   communication  may   lead   to  wider   adoption  of  innovative,  nature-­‐based  strategies.      

Vertical   collaboration   is   needed   to   align   funding   sources  with   local   goals   and   needs.     And   horizontal  collaboration   is   needed   to   align   regional   plans   and   create   a   vision   of   coastal   flood   mitigation   that  incorporates   nature-­‐based   strategies   into   a   flexible,   adaptive   shoreline   rather   than   a   piece-­‐meal  collection  of  structural  approaches.    Hazard  mitigation  and  coastal  planning  efforts  are  divided  into  two  physical  offices,  and,  according  to  respondents,  these  offices  rarely  speak  to  one  another  or  coordinate  their  efforts.    However,  such  coordination  will  be  necessary  to  prepare  and  protect  California  coasts  for  the  long-­‐term  effects  of  climate  change  and  natural  hazards.      

   

Funding  Barriers  –  Use  of  FEMA  Hazard  Mitigation  Funding  for  NBS    A  perceived  lack  of  funding  is  a  core  issue  referenced  in  all   interviews.    We  have  already  discussed  the  role  of  funding  in  collaboration  and  data  collection,  but  funding  also  plays  a  role  in  the  way  that  NBS  are  perceived:   as   “green”   ecological   projects   or   as   flood   mitigation   projects.     From   our   interviews   with  California  planners,  we  draw  two  broad  conclusions:    

(1)  Many   planners   have   not  made   the   connection   between   nature-­‐based   strategies  and  hazard  mitigation  or  with  FEMA  as  a  potential  funding  source.      

(2)  If  planners  do  make  the  connection  between  FEMA  and  NBS,  most  planners  believe  that  FEMA  regulations  would  make  the  use  of  FEMA  funding  for  NBS  impossible.    

Many  respondents  felt  that  existing  hazard  mitigation  funding  is  too  specific  and  could  not  be  applied  to  broad   and   ambiguous  projects   such   as   nature-­‐based   strategies.    One  planner  wanted   to   collect  more  data  relevant  to  nature-­‐based  strategies,  but  believed  she  could  not  get  the  necessary  funding  to  pursue  this   research.     Other   officials   expressed   the   opinion   that   if   FEMA   intended   to   fund   NBS,   the   agency  would  have  made  an  explicit   statement   to   that  effect.     Still  others  believed   that  NBS  would  not  meet  FEMA’s   cost-­‐benefit   analysis   requirements.     In   a   related   legal   analysis   of   FEMA’s   hazard   mitigation  funding,  our  policy   lab  concluded  that  there  are  no   legal  barriers  to  the  use  of  FEMA  funding  for  NBS.    

Potential  Solutions  to  Collaboration  and  Coordination  Barriers    

• Provide  a  mechanism  for  local  officials  to  provide  feedback  to  federal  and  state  agencies  on  funding  processes  and  funding  needs.    

• Hold  in-­‐person  training  events  on  NBS  or  related  topics  (flood  mitigation,  hazard  mitigation  funding);  provide  time  and  space  to  encourage  local  planners  to  network.    

• Provide  funding  to  support  collaborative  planning  efforts;  or  allow  portions  of   larger  grants  to  be  used  for  planning  efforts.    Provide  more  lead-­‐time  in  advance  of  funding  applications  to  give  applicants  time  to  explore  their  options.    

• Create  an  online  forum  for  exchange  of  information  on  flood  mitigation  and  NBS.    • Identify   coastal   regional   groups   to   promote   functional   collaboration   areas   (e.g.   Monterey  

Bay)  according  to  ecological  and  geological  markers  rather  than  political.

Rather,   a   lack   of   communication   (or   miscommunication)   between   FEMA   and   local   jurisdictions   has  created  the  false  impression  that  only  structural  solutions  would  qualify  for  hazard  mitigation  funding.  

Planners  already  struggle  through  the  process  of  applying  for   funding  for  their  current  projects,  which  take   significant   time  and   resources  and   can  be   frustrating  and   fruitless.    Given   their   time   constraints,  few   planners   have   the   space   to   consider   new   and   unorthodox   funding   opportunities.     As   a   result,  planners  are  often  unwilling   to   invest   the   time  or  energy  necessary   to  determine  whether  NBS  would  meet   FEMA   requirements.     They  would   be   far  more  willing   to   engage   FEMA   funding   if   it   were   clear  whether  or  how  NBS  could  meet  the  FEMA  application  requirements.    

 

Political  Will  Barrier  Political  will  barriers   relate   to  pushback   from   influential   stakeholders  at  efforts   to  adopt  nature-­‐based  strategies   for  coastal  hazard  mitigation.    A  political  will  barrier   includes   issues  relating   to  “politics  and  the   political   process   (e.g.,   property   rights   issues   .   .   .   fear   of   legal   repercussions,   resistance   to  collaboration).”     This   also   includes   the   “inability   to   message   the   story   in   an   appealing   or   politically  salient   way,”   “public   or   stakeholder   opposition   to   choices,”   or   “resistance   from   affected   parties”  (Moser,  p.  64-­‐66).    

Local  planners  believe  community  members  are  often  supportive  of  plans  to  deal  with  climate  change  and  sea  level  rise.    Pushback  occurs  when  the  public  does  not  understand  how  a  certain  plan  will  affect  their   homes   and   lives.     The   public   is   often   familiar   with   nature-­‐based   strategies   as   a   conservation  strategy  (e.g.  wetland  restoration  to  maintain  habitat)  but  not  as  flood  mitigation.    As  a  result,  they  may  be  skeptical  of  the  ability  of  NBS  to  protect  coastal  homes.    This  is  tied  to  the  lack  of  technical  standards  and  monitoring  and  evaluation  data  discussed  above.    Without  technical  standards  or  performance  data,  planners  feel  unable  to  convince  the  public  that  NBS  will  work.    Furthermore,   if  NBS  do  fail   to  protect  citizens,  planners  also  worry  about  potential  legal  liability  and  political  repercussions.      This  uncertainty  can  make  planners  and  city  councils  unwilling  to  invest  in  NBS,  even  though  they  are  aware  of  the  long-­‐term  benefits.    

Addressing  the  data  concerns  discussed  above  would  provide  planners  with  more  scientific  evidence  to  support  the  use  of  NBS  and  reassure  planners  and  the  public  that  NBS  are  being  properly  implemented.    

Potential  Solutions  to  Funding  Barriers    

Most  of  these  suggestions  would  require  action  by  FEMA:      

• Publish  an  official  statement  endorsing  the  use  of  nature-­‐based  flood  mitigation  strategies.    • Clarify   which   hazard   mitigation   funding   programs   NBS   would   be   eligible   for;   Provide  

guidance  on  the  type  of  information  that  would  be  required.    • Provide  clearer  guidance  (or,  to  also  promote  collaboration,  hold  an  in-­‐person  workshop)  on  

the  benefit-­‐cost-­‐analysis  (BCA)  (and  software)  and  how  NBS  can  meet  the  BCA  requirements.    Develop  an  FAQ  section  on  the  FEMA  website  dedicated  to  NBS  in  hazard  mitigation  funding  and  solicit  questions  from  local  planners.      

• Make   the   information   from   successful   applications   publicly   available   (or   available   on  request)  to  potential  applicants  so  that  planners  can  see  the  type  of  information  that  needed  to  be  collected  in  order  to  pursue  NBS.

A   demonstration   project   that   was   monitored   and   evaluated   both   during   and   after   implementation  would  also  create  greater  public  familiarity.    

 

 

City  and  county  officials  in  California  recognize  that  despite  the  acknowledged  benefits  of  nature-­‐based  flood  mitigation   strategies   for   protecting   coastal   development   and   ecosystems,   there   are   substantial  barriers   to   shifting   away   from   traditional   structural   approaches   and   towards   nature-­‐based   strategies.    These  barriers  include  lack  of  specific  data,  technical  standards,  regional  and  inter-­‐agency  coordination  and  collaboration,   and  political  will.    However,  none  of   the  barriers   identified  by   coastal  planners  are  insurmountable.    Identifying  the  barriers  is  only  the  first  step.      

This  report  identifies  specific  barriers  as  reported  by  city  and  county  officials  and  suggests  some  actions  that  could  be  taken  by  FEMA  or  The  Nature  Conservancy  or  other   interested  organizations   to  address  these  barriers  and  promote   the  use  of  NBS.     Implementing   these  suggestions  or  otherwise  addressing  the   barriers   identified   to   nature-­‐based   solutions   may   help   protect   California’s   coast   and   coastal  infrastructure  for  the  future.

Potential  Solutions  to  Technical  and  Information  Barriers    • Develop  technical  engineering  standards  to  guide  the  implementation  of  NBS.      • Develop   a   standard   monitoring,   evaluation,   and   assessment   process   to   document   the  

performance  of  NBS.      • Create  an  online  “toolkit”  of  nature-­‐based  flood  mitigation  strategies.  Include  information  on  

technical   standards,   implementation,  monitoring,  and  cost.  Especially   important   to  provide  information   on   when   and   where   particular   NBS   are   most   appropriate.     Identify   success  stories  in  California  to  serve  as  examples.    

• Clarify  funding  guidelines  to  expressly  and  explicitly  state  whether  NBS  are  eligible;  develop  a  “Frequently  Asked  Questions”  set  focused  on  NBS.  In  particular,  FEMA  needs  to  clarify  how  NBS  information  can  be  used  in  the  cost-­‐benefit  analysis  tools.
